The DMCA has been used by media giants such as Viacom to harass web users who share content; but a group of internet freedom advocates are exploiting a little-used clause in the copyright act to fight back. The Electronic Freedom Foundation has launched a suit against Viacom after a spoof video was taken down from Youtube. Viacom, which owns networks such as MTV and Comedy Central, ordered Google to remove more than 100,000 clips of shows such as the Colbert Report, the fake news show with TV comic Stephen Colbert. But one of the clips taken down at Viacom's request was, not the show itself, but a parody of it: the DMCA allows for a media owner to be sued for misrepresentation if they wrongly claim copyright violation in making a takedown request. Here's the irony: the 1998 DMCA, which arbitrarily extended copyright right for decades, has long been hated by internet anarchists; now Google's using its provisions to fend off content owners; and free speech advocates are using its provisions to cause trouble.
